E. K. BRECKENRIDGE, OF MERIDEN, CONNECTICUT.

, IMPROVED WINDOW-SPRING.

.T0 all whom, it Hetty concern,.-

Be it known that I, E. K. BRECKENRIDGE, of Meriden, in the county of NewHaven and State of Connecticut, have invented a new and usefulImprovement in Window-Springs; and I do hereby declare the following tobe a full, clear, and exact description of the same, when taken inconnection with the accompanying drawings and the letters otl referencemarked thereon, and which said drawings constitute part of thisspecification, and represent, in

Figure 1, a front side view; Fig. 2, a face view; Fig. 3, a back sideView, and in Fig. 4 a rear view.

Same letters indicate corresponding parts in the several figures.

My invention relates to improvements in that class ot' windowspringswhich are de signed to apply to the window-frames for the purpose ofholding or securing the sash up or down at any required point.

To enable others skilled in the art to construct and use my improvedwindow-spring, I will proceed to fully describe the same as illustratedin the accompanying drawings.

A is the face-plate, by which the spring is secured to the frame 5 B,the latch, cart with ating the latch. D is a spring secured to the plateA by being passed under a yoke, d, cast upon the plate for the purpose.The lower 4end of the spring bears upon the latch B, as seen in Figs. land 3, to force the latch out, as in Fig. 1, in which position, strikinginto a notch in the sash prepared for the purpose, retains the sash inthat position until released by raising the lever, as in Fig. 3, whichdraws the latch from its hold upon the sash, in which position the sashmay be moved as desired until the spring or latch is released andallowed to ily out, as in Fig. 1, catching another notch in the sash inthe usual manner for windowsprings of this nature. Y

By this construction of the plate and latch they are iinishedsufficiently to put together as they come from the foundry, simplyrequiring to place the latch in its place and insert the spring. Thenecessity of drilling or other mechanical operation is entirely avoided,an extremely cheap, simple, and durable windowspring produced.

Having therefore fully described my invention, what I claim as new anduseful, and desire to secure by Letters Patent, is The combination ofthe plate A, latch B,

and spring D, constructed, as described, to operate in the mannerspecified.
